Title: Method for preparing metallocene catalyst
Inventor: GAUTHIER WILLIAM J
IPC: C08F10/00
Filed: 2002-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for preparing a metallocene catalyst. SOLUTION: This process for the preparation of a supported metallocene catalyst incorporating metallocene and cocatalyst components on a support. There is provided a particulate catalyst support material in which an alumoxane co-catalyst is incorporated onto the support particles and contacted with a dispersion of a metallocene catalyst in an aromatic hydrocarbon solvent. The metallocene solvent dispersion and the alumoxane-containing support are mixed at a temperature of about 10 deg.C or less for a period sufficient to enable the metallocene to become reactively supported on the alumoxane support material. The supported catalyst is recovered from the aromatic solvent and then washed optionally with an aromatic hydrocarbon and then sequentially with a paraffinic hydrocarbon solvent at a temperature of about 10 deg.C or less.  The washed catalyst is dispersed in a viscous mineral oil having a viscosity which is substantially greater than the viscosity of the paraffinic hydrocarbon solvent.

Title: Drum type drier
Inventor: KAWAMURA TAMOTSU
IPC: D06F58/28
Filed: 2002-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To improve correctness of determination of the dryness degree of the laundry.  <P>SOLUTION: In the beginning of drying operation, drum rotation is reversed every prescribed time for preventing entanglement of the laundry (S1). The drum outlet temperature is fluctuated in accordance with rotation directions of the drum. The cooling water temperature after dehumidification gradually rises in the beginning of drying, and then it becomes roughly constant. As the laundry is becoming dry, it starts to fall. A drying state is detected based on such a temperature change (S3, S4), and as drying proceeds to a certain degree, the drum is changed to be rotated in one direction only (S5). The drum outlet temperature can thus be stably and correctly detected, thereby drying completion time can correctly be determined based on difference between both temperatures (S6-S8).  <P>COPYRIGHT: (C)2003,JPO
